These cruise ships will either use diesel-electric engines or gas turbines. Without a source of power, these huge cruise vessels would be nothing more than drifting aimlessly hotels. A large number of older ships use diesel reciprocating engines for generating power for propulsion.

How Big is a Cruise Ship Engine?
Now, she helps over 1 million people per month to plan their perfect cruise holidays. Even if you choose to stay in one of the most expensive suites on the ship, this doesn’t guarantee that you’ll be able to rest undisturbed. There are plenty of other things that could keep you awake at night on a cruise ship.
Cruise Ship Facilities for Passengers
The RoPax vessel uses LNG as prime fuel and MDO (marine diesel oil) as secondary fuel. Both self-unloading dry bulk vessels were China-built (by Chengxi Shipyard Co Ltd / subsidiary of CSSC) and scheduled for deliveries in 2021. Big ships require much power, so they might have more than one emergency generator. All ships are supplied with emergency generators to maintain vital electrical power. Backup generators are located higher up and also outside engine room spaces to isolate them from damage or fire. Wartsila's fuel engine package was specifically designed to reduce fuel consumption.
Are Passengers Safe if There Is Engine Failure?
While berthed, the ship was successfully provided with LNG at all the itinerary's ports of call (Hamburg, Rotterdam, Le Havre, Southampton, Zeebrugge). Fincantieri used Promas Lite propulsion for all Viking Ocean liners. Currently, NCL Norwegian Epic has two rudders with conventional non-Azipod screws. But how does she manage to maneuver if they can push in one direction only? One option is to make them bigger and more effective when maneuvering, another is to add additional mini-pods or install full-sized pods. Only time will tell if any of these will actually ever happen.
Shore-to-Ship Power Supply
Modern cruise ships carry a gyro compass and a magnetic compass. The gyro compass consists of a fast-rotating disk, usually positioned in a gimbal. It is a non-magnetic compass oriented parallel to the axis of rotation of the earth and thus indicates the north-south direction. The signals emitted by special navigation satellites are picked up by the cruise ship through a special antenna. On board, a computer converts these signals into the exact position of the ship at a given time. On large ships, the position indicator is constantly recorded in a so-called electronic nautical chart.
They would drift aimlessly at sea and would lack any form of propulsion. Looking at the sheer size of these vessels makes one wonder how large an engine needs to be to maneuver the ship successfully in water. The SS Norway was crucial in bringing international attention once again to the dangers of using super-heated steam to power ships.
Marine diesel engines
I would have liked to see the engine room but that will not happen, in the control room they have a monitor for the engine room camera so they can watch the engine. True they do not take you to the actual engine room, however there are monitors in the control room to look at. Carnival sent me information about it and they visit alot of "behind the scene" things. My DH and some of the others would like to see the engine room, but if this is just a room with lots of computers and controls I'm not sure if that is what they really want to see. This protective coating must be inspected and maintained at regular intervals to keep the ship safe from corrosion. The AIDAprima ship's first successful test run for LNG supply was in Hamburg Germany on May 7, 2016.
Crew Accommodations and Facilities
On May 25, 2003, one of the four boilers on the SS Norway exploded while she was docked at the Port of Miami, and luckily no passengers were hurt. The SS Norway was launched in 1962 (originally as the SS France) and was the longest cruise ship in the world (316 metres) until the RMS Queen Mary 2 (345 metres) was launched in 2004. While operating as the SS France she had eight boilers which provided 175,000 hp and gave her a cruising speed of 31 knots.
Marine nuclear power engines
The program's completion was scheduled before January 1, 2021. The project also includes all vessels to be upgraded with shore power capabilities. The above photo shows Oasis-class ship propulsion Azipods (2 units) before being mounted onto the hull.
The largest cruise ship, Wonder of the Seas, utilizes six marine-diesel sets, with each composed of three 16-cylinder Wartsila engines. You see not only engine controls, but firefighting controls, environmental controls, temperature, etc. While these tanks and treatment systems are incredibly sophisticated and far more sanitary than you may assume, they still sit out of view of passengers.
"Rotor Sail Solution" is an innovative technology developed by the company Norsepower Ltd (Finland) in 5 years. It reduces fuel consumption and also COx emissions up to 900 tons per year (depending on wind conditions). LNG is natural gas, which consists of 90% methane and 10% ethane.
This explains why they are almost always located in the ship’s hull. The hull sits below the waterline, covering a cruise ship’s entire underbody. This means it extends from the bow of the ship right to the stern. In terms of its height, it also runs from the waterline down to the ship’s keep, which is the lowest point of any ship.
It will be up to the captain and the chief engineer to determine if the vessel can continue if one of their engines isn’t working properly. If the captain feels the cruise ship will not be able to function, they will consider other options. Due to high specifications and standards, it is rare for a cruise ship to experience engine failure. The International Maritime Organization has a “Safe Return to Port” initiative.

If the electrical cables aren't truly redundant, even ships that feature two engine rooms suffer power failure. Cunard QE2, for example, consumes daily 380 tons of fuel when traveling at 29 knots speed and carries fuel enough to sail for 12 days. Usually, ships fill up at various seaports and use fueling barges as floating gas stations. Vessels use lower-grade diesel which tends not to burn as purely as diesel-powered road-going vehicles. As the ship size increases, the demand for electrical power increases. Some large ships depend on two types of power source that gives power to the engine, one for propulsion and the other for electric power.
